SPECIFICATION. forming-part of Letters Patent ;Nc. 270,172, dated January 2, 41883.

Application tiled March 30, 1882, (Model.)

To all whom it may concern Be it known that I, JACKSON R. BAKER, of

Jersey City, Hudson county, State of New Jersey, have invented a new and useful Improvenient in Locks for the Lids of Gar-AxleV Boxes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying sheet of drawings, making part ot' I@` this specification.

This invention isin the nature ofan improvement in locks for the lids of car-axle boxes; and the invention consists in a car-axle-box lid provided with a shaft, with locking devices ixed to its ends and resting in bearings, in combination with a spiral spring and lugs cast on the side of the box to engage with the locking devices; and the invention also consists in the means, hereinafter described, for excluding 2o dust :from the interior of the box, and from said shaft and its bearing and spring. ,j

In the accompanying sheet oi'drawings, Figure l is a side view ot' myinvention; Fig.2, a front View of same; Fig. 3, a view of under side of plate, shaft, and spring; Fig. 4, a crosssection of plate, box, and shaft, taken in the line a: zo, Fig. 3.

Siniilarletters of referenceindicate like parts in the several figures.

The purpose of this invention is to construct the lid of a car-axle box so that itcan be readily opened and as readily fastenedl or locked without employing a wrench, and without lia` bility of becoming detached or the lid unfastcned. To that end I construct the lid A ofthe axle-box with beni-in gs a cast on the face thereof, a recess, b, being also cast on the face of this lid. A plate, B, is provided, of cast metal or otherwise, with bearings o alsoformed there- 4.o on, and a cavity, d, extending the entirelength thereof, between the bea-rings o. Resting in the hearings a is placed a shaft, O, so that it may freely turn in said bearings, and surrounding this shaftywith'oiie of its ends fixed thereto and its other end fixed to the plate B, is a spiial spring, D.

To the ends ofthe shaft G, which ends project on each side of the piate B, are secured lock-catches E, and `onto the lid A are cast `5o lugs e, and to the sides of the box F are also cast lugsf. The upper edge or side of the lid A has fornied onit a lip, G, and the face of the box F, to which the lid A is secured, extends upward, as at 7c, Fig. l.

Now, when my lid and box are constructed substantially as above described, the shaft G is turned on the bearings o until the spiral spring D has a sufficient amount of tension given to it, and when the plate B is placed on the face vof the lid A, so that the shaft G will be received 6o in the bearings con the face of the lid and the spring Dand shaft C will be received within the recess b therein, the plate B is screwed fast to the lid A. The locking-catches E then beingin contact with the lugs e of the lid, they prevent the shaft O from revolving in a way that would uncoil to some extent the spring D. and thereby lessen its tension. The lugs fon the side of the box F, having entered into notches g, formed in the under side of 7o' the locking-catches E, effectually lock. the lid A in place to the box -F and close the opening therein. Now, to unlock the catches E it is simply necessary to raise themnntil the notches g therein clear the lugs nf on the side of the box F, (the shaft C turning in its bearings, admitting of this operation.) The lid A being open, it will close and lock by its owngravity. For this purpose the front lends of the locking-catches E are beveled, and the 8o front of the lugs fon the sides of :he box F are somewhat rounded, so that as the lid descends by gravity the beveled ends ofthe locking-catches E are brought in contact with the lugs f, causing the shaft C and its spring D to yield until the lid is locked, as before described, by the entering of the lugs-fot' the box Fin to the notches g of the lock-catches E. When the lid A is in this way locked to the box F the lip G on the upper side of the lid A lits over 9o the projecting part la otl the face of the box F, thereby excluding dust froin the axle-journal within the box F. L

To also exclude the dust froin the bearings a o and the shalt O and the spring D, I forni recesses Z in the face of the lid A, into which recesses is run a soft metal alloy, similar to the Babbitt metal, this metal forming a soft bearing-surface between the lid A and the plate B,

and effectually closing the joint between them roo and preventing the dust from entering.` i

Having now described my invention, what I .2 l erom/2 claim as new, and desire to secure by Letters Patent, is- -f 1. A car-axle box with its lid provided Vwith e rotating shaft; and a coil-spring around the same, and with lock-catches xed to the ends of said shaft, in combination with lugs east on said box to engage With said lock-catches,

. whereby the lid is secured to the box, substantvialiy as is shown and described.

2. The box provided with the projecting por- .by a packed joint to said 1id,substantially as shown and described, for the purpose of excluding dust from the box and fastening.

3. In a car-axle box, thecomhination of a rotating shaft with a removable plate and beveled and notched locking-catches, substantially as is shown and described.

4. In a car-axle box, the combination of a rotating shaftJ and locking-catches fixed thereto, with lugs e, secured to the lid A of said box, substantial] y as and for the purpose described.l
